DialogFragment animation of layout and "Attempting to destroy the window while drawing!" error

Question

I have a DialogFragment which has some animations of some of the layouts inside its view. When I dismiss the dialog, I want to perform an animation and when the animation has ended, perform the dismiss operation.

Step1: Call the fragment from my activity:

myDialog.show(getSupportFragmentManager(), "");

Step 2: After the user had completed the job with the dialog, he presses a button. That button calls an animation and after that I want the dialog to disappear:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View layout = inflater.inflate(R.layout.my_layout, null);

        layMain = (LinearLayout) layout.findViewById(R.id.layMain);

        TextView btnCancel = (TextView) layout.findViewById(R.id.btnCancel);
            btnCancel.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View arg0) {
                    final Animation anim = AnimationUtils.loadAnimation(getActivity(), R.anim.translate_to_bottom);
                    anim.setAnimationListener(new AnimationListener() {

                        @Override
                        public void onAnimationStart(Animation animation) {

                        }

                        @Override
                        public void onAnimationRepeat(Animation animation) {

                        }

                        @Override
                        public void onAnimationEnd(Animation animation) {
                            dismiss();
                        }
                    });
                    layMain.startAnimation(anim);
                }
            });
.....

When the animations ends, the dialog gets dismissed but I get this error on logcat

E/ViewRootImpl(25507): Attempting to destroy the window while drawing! E/ViewRootImpl(25507): window=android.view.ViewRootImpl@427348e0, title=com.mypackage/com.mypackage.MyActivity

How can I prevent this ?

Later edit: if I am using it without any animation, everything works fine and no error is shown on logcat. So I suppose it has to do something with the animation.

The animation I am using:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false" >

  <translate
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromYDelta="0%p"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="80%p" />

</set>

Answer 1

The only solution that works so far, without throwing an error is this:

@Override
public void onAnimationEnd(Animation animation) {
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            dismiss();
        }
    }, 10);

}

I am open to any other sugestions

Answer 2

You have pass fragment context as a getSupportFragmentManager(). So you have to change it:

myDialog.show(getFragmentManager(), "");
